I get a lot of really annoying sudden sharp neuropathic shooting pains for which I take gabapentin which much reduces their frequency and strength, and helps with all altered sensations.
There may well be other treatments, of course, so you’ll just have to wait and see what your neuro offers you.
With a bit of luck, that will either reduce or even go away as the relapse resolves. Your body will do its level best to heal or at least to find workarounds for more lasting damage. As others have said, there are symptom drugs to help you cope with any residuals that are troublesome to you.
But the main thing with RRMS is to try to stop or at least minimise future relapses, and that means getting on disease modifying treatment if that is available to you. It won’t deal with the trouble you have now, but it should help ward off future attacks. It is often more effective to avoid or minimise future MS relapses than to deal with ones that have already arrived.
Yes, there is a wide range of treatments, all with their own balance of benefits and risks. The main part of this MS Society site has good information.
